Correct answer: C
A modem works by converting signals between digital and analog forms.
At the sender side, the computer generates data in digital form, using 0s and 1s. For transmission over analog media such as traditional telephone lines, the modem converts this digital data into an analog signal. This process is called modulation.
At the receiver side, the modem converts the analog signal back into digital data. This reverse process is called demodulation.
Therefore, during transmission from the sender side, the data is first converted from Digital to Analog.
